radeon/llvm: Rework how immediate operands are handled with SI

Immediate operands were previously handled in the CodeEmitter, but that
code was buggy and very confusing.  This commit adds a pass that simplifies
the handling of immediate operands by spliting the loading of the
immediate into a sperate insruction that is bundled with the original.
